BRIDLE-STRAP-ATTACHING TIP.

Specification of Letters Patent. Patented N 16 1920 Application filed March 26, 1920. Serial No. 369,021.

To all whom it may concern:

Be it known that I, YVILLIAM F. OHST, a citizen of the United States and resident of Long Branch, county of Monmouth, and State of New Jersey, have invented a new and Improved Bridle-Strap-Attaching Tip, of which the following is a full, clear, and exact description.

This invention relates to improvements in piano actions and has particular reference to a means for attaching the bridle-strap to the back-stop shank.

Heretofore a great deal of diiiiculty has been experienced in replacing a broken bridle-strap, as it has been necessary to remove the back-stop shank from the hammer buttand insert the extremity of the new bridle-strap in the opening and then reinsert the back-stop shank.

It is, therefore, one of the principal objects of the present invention to overcome the above recited obj ections by providing an attaching tip for the bridle-strap which obviates the necessity of removing the backstop shank when it is necessary to replace the bridle-strap.

Another object in view is to provide an attaching tip for the bridle-strap which includes means adapted to coact with a tool for positioning the same, thus eliminating the necessity of removing any of the parts of the action.

A further object of the invention is to provide an attaching ti which is of extremely simple construction, inexpensive to produce and efficient in purpose.

With these and other objects in view some of which will be more readily apparent hereafter, reference is made to the accompanying drawings forming a part of this specification, and in which- Figure 1 is an elevation of a portion of a piano action illustrating the manner in which the tip is positioned.

Fig. 2 is a detail perspective view of a portion of a bridle-strap with the tip applied thereto.

Fig. 3 is a view of the blank from which the ti is formed.

Re erring to the drawings by characters of reference which denote like parts throughout the several views thereof, 10 designates the hammer butt of a piano action, 11 the back-stop and 12 the back-stop shank, the back-stop being provided with the usual opening 13 therethrough for the passage of the bridle-strap 14. It is the usual practice to insert the extremity of the bridle-strap 14 in the opening 15 of the hammer butt which receives the back-stop shank 12. However, when the bridlestrap wears and breaks, it necessitates the removal of the back-stop shank in order to insert the extremity of a new bridlestran therein. This necessitates the removal of a number of parts of the action which not only consumes time and labor, but puts the piano out of action until the glue which normally retains the backstop shank in the opening 15, has dried.

The means hereafter described serves to replace a broken bridle-strap instantaneously and in such a manner as to permit of the immediate use of the piano. In carrying the invention into practice and in the preferred form illustrated, the tip consists of a single strip of material 16, preferably sheet metal which is bent upon itself as illustrated to provide superposed pockets 17 and 18, the mouths of which are disposed at 0pposite ends of the pockets. The upper pocket 17 is formed by the reversely bent end 19 of the strip, and the lower pocket by the reversely bent end 20 of the strip. The upper pocket 17 receives the terminal of the bridle-strap 14 which is secured therein by means of a tack 21, said tack also serving as an attaching element for securing the tip to the back-stop shank. The lower pocket 20 is designed to receive a screw driver and other tool which is inserted therein. The bridle-strap is preferably extended around the portion 20 of the tip as illustrated.

In applying the tip to the back-stop shank, the pocket 18 is positioned over the end of the screw driver and the same is inserted through the opening 13 in the back-stop 11 with the point of the tack extending up ward. It is only necessary to reach over and exert a pressure with the hand on top of the back-stop shank and at the same time force the tack into engagement with the back-stop shank which will force the tack into position.

While a single and preferred embodiment of the tip has been illustrated and described, it is understood that variations and modifications falling within the scope of appended claims may be resorted to when found ex edient.

aving thus described my invention, what I claim as new ters Patent is:

l. A tip for a'taching a bridle-strap to the back-stop shank of a piano action comprising a member having a tool receiving pocket, a bridle-strap terminal receiving pocket and means for securing the bridlestrap terminal Within its pocket, said means also serving as a device for attaching said tip to the back-stop shank.

"acter described, bridle strap, of remity thereof for e backstop shank neans comprising a a pocls having for retaining the bridle-strap terminal Within its embracing portion, said means serving also as an attaching device for securing the tip to the backstop shank.

5. In an attaching tip for a bridle-strap, nember formed of a single strip of material bent upon itself to provide spaced portions for the reception of the extremity of the bridle-strap, a common means for securing the extremity of the bridle-strap between said spaced portions, and for securing the bridle-strap to the back-stop shank.

6. A device of the character described, consisting of a strip of. material having the end portions thereof reversely bent over the central portion and lying parallel therewith to constitute pockets adapted to respectively receive and embrace a tool and the bridlestrap terminal which extends from the open end of its pocket and embraces the tool pocket, and means for retaining the bridlestrap terminal Within its pocket, said means extending through the reversely bent portion of said pocket to con titute an attaching element for the device.

7. The combination with a bridle-strap of ans adapted to be removably carried by one extremity of the same to brm'ide for its attachment to the back-stop shank, said means comprising tip formed of a strip of material having opposite ends reversal) bent inward to provioe a central. wall and outer walls overlying and spaced from said central well, one of said outer Walls having a central aperture, and a tack adapted to pass through oneextremitv of the bridlestrap and the aperture in the outer apertured Wall for retaining the bridle-strap tremity to the tip, the pointed end of the tack projecting from said aperture to atl'ord means for securing the tip and bridle-strap extremity to the back-stop shank.
